Screw ndi imodzi mwa zomangira zomwe wamba, ndipo pali mitundu yambiri ya zomangira, kuphatikiza zomangira zomangira mchira ndi zomangira zokha.
Mchira wa kubowola mchira wononga ndi mawonekedwe a kubowola mchira kapena nsonga mchira, ndipo safuna ntchito yothandizira. Ikhoza kubowoledwa mwachindunji, kuponyedwa, ndi kutsekedwa pazitsulo ndi maziko, kupulumutsa kwambiri nthawi yomanga. Poyerekeza ndi zomangira wamba, zimakhala ndi mphamvu zolimba kwambiri komanso zogwira, ndipo sizimamasuka ngakhale zitaphatikizidwa kwa nthawi yayitali. Ndikosavuta kugwiritsa ntchito pobowola bwino ndikugogoda kuti mumalize ntchitoyi nthawi imodzi. Makamaka pakuphatikiza zomanga, zomanga, zokhalamo ndi malo ena, zomangira zodzibowolera zokha ndi zomangira zabwino kwambiri zachuma malinga ndi magwiridwe antchito, mtengo komanso kudalirika.
Zomangira zomwe zimadziwikanso kuti zomangira mwachangu, ndi zomangira zitsulo zomwe zakhala zikuyenda bwino komanso kugwedezeka. Zomangira zomangira pawokha nthawi zambiri zimagwiritsidwa ntchito polumikiza zitsulo zopyapyala (monga mbale zachitsulo, zomangira, ndi zina). Mukalumikiza, choyamba pangani bowo la pansi la ulusi wa gawo lolumikizidwa, ndiyeno potola wononga poto yolowera pansi pa dzenje lolumikizidwa.
① Kusiyanitsa pakati pa zomangira zobowola mchira ndi zomangira zodzibowola malinga ndi zida: zomangira zoboola mchira zimakhala zamtundu wa zomangira zamatabwa, pomwe zomangira zomwe zimakhala zamtundu wina wodzitsekera.
② Kusiyanitsa pakati pa zomangira zobowola mchira ndi zomangira zodzibowolera zokha malinga ndi momwe zimagwiritsidwira ntchito: Zomangira zamchira zimagwiritsidwa ntchito kwambiri kukonza matailosi amtundu wachitsulo ndi mbale zoonda pamapangidwe azitsulo. Chinthu chachikulu ndi chakuti mchirawo uli mu mawonekedwe a mchira wobowola kapena mchira wosongoka. Mukagwiritsidwa ntchito, palibe chifukwa chothandizira kukonza, ndikubowola, kubowola, kutseka, ndi ntchito zina zitha kumalizidwa mwachindunji pazinthuzo kamodzi, ndikupulumutsa nthawi yoyika. Zomangira zodzigudubuza zimakhala zolimba kwambiri ndipo zitha kugwiritsidwanso ntchito pazinthu zolimba kwambiri, monga mbale zachitsulo. Imakhala ndi torque yocheperako komanso yotseka kwambiri.
③ Kusiyanitsa pakati pa zomangira zomangira mchira ndi zomangira zomwe zimagwirira ntchito: Zomangira zomangira mchira ndi zida zomwe zimagwiritsa ntchito mfundo zakuthupi ndi masamu pakuzungulira kozungulira komanso kukangana kwa zinthu kuti pang'onopang'ono kumangitse magawo amakanika a zinthu. Zomangira zomangira mchira ndi zomata zokhala ndi mitu yobowola yodziboolera yokha kumapeto kwa screw. Zomangira zomangira pawokha nthawi zambiri zimagwiritsidwa ntchito polumikiza zitsulo zopyapyala (monga mbale zachitsulo, zomangira, ndi zina). Mukalumikiza, choyamba pangani bowo la pansi la ulusi wa gawo lolumikizidwa, ndiyeno potola wononga poto yolowera pansi pa dzenje lolumikizidwa.
